Stalled negotiations regarding transfer procedures have prompted Serie A players to call for a strike of the games to be played Dec. 11 and 12.

Leanardo Grosso, vice president of Associazione Calciatore Italiana, the players' union, said, "We are really disappointed because we were open to negotiate and to find common ground, but no agreement has been reached."

A pending strike was called off in September when the two sides agreed to negotiate. The players contend they are often forced into transfers in the final year of their contracts.
